Abstract

If we observe the sun in the continuum of its spectrum, the surface shows a mosaic-like intensity structure that is called “granulation” in astrophysics, Fig. 1. This structure was first observed in 1877 by the French astronomer Jansen who also gave it its name. Since the “discovery” of a convectively unstable layer in the solar atmosphere by Unsold in 1931, in which energy transport occurs by means of convection rather than by radiation, the granulation has been considered a consequence of the convection zone.
